LIQUID CRYSTAL ALIGNING AGENT, LIQUID CRYSTAL ALIGNMENT LAYER, METHOD FOR PRODUCING LIQUID CRYSTAL ALIGNMENT LAYER, AND LIQUID CRYSTAL DISPLAY ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal display element achieving a desired response time and/or expression of improved display quality, a liquid crystal alignment layer achieving a desired response time and/or improved display quality with the liquid crystal display element and a production method thereof, and a liquid crystal aligning agent capable of forming the same.

SOLUTION: A liquid crystal alignment layer is formed by using at least one selected from polyimide obtained by reaction of diamine with tetracarboxylic acid dianhydride, polyamic acid as its precursor, or polyamic acid derivative, and a liquid crystal aligning agent containing a photopolymerizable monomer and/or a photopolymerizable oligomer. The liquid crystal alignment layer is used for a liquid crystal display element.
